How do other engineers here on HN feel about it?
Today? I'd be running around like an excited child, given half a chance. Probably hugging people I know are comfortable with it. I recognized I really do like that energy, and I only live once.
Not saying people who prefer a more restrained celebration are not valid in their preference! Everyone is a little different, and that is a good thing. At my workplace we like to have multiple ways to celebrate a milestone, because it's important that everyone can participate if they want. For example, we might have a team lunch/party (pre covid) for folks who like that, but also, say, personalized notes sent out, or office posters made of the achievement with participants' signatures on it (optional), and companywide announcements (again, representation optional).
For the record the only movie that routinely tears me up is Apollo 13. Specifically, when they land, and the people in Mission Control are shown. Some of those people have a lifelong bond because of that event, I'm sure. That's important to me.
Moreover such complex missions can go either way, I think it is perhaps better to be even-tempered and business like about it.
That's OK. I not only don't celebrate that way, it'd make me uncomfortable even for a peer I like to hug me out of excitement. It's not what I want but it's what other people want and it seems to be the norm.
You may end up learning that this may hold you back professionally at some point unless you can stay in a role that doesn't value social signaling, as these behaviors are basically expected, and not performing them will get you excluded, unless you find a way to surround yourself with people who have shared views on this sort of thing, which is really hard to find out because it's implied.
At least that's what I've been thinking this past year of isolation where I have been very happy to not feel obliged to do the social things everyone else so desperately wants to go out and do together.
I'm on the lookout for backcountry camping trips I can do once things are "back to normal" so I can continue my isolation while everyone is at restaurants and parties.
I am gonna be really irresponsible, once I got my vaccine shot.
